Description
Technical field
The invention belongs to Physical Experiment clothing arts, and in particular to a kind of buoyancy measurement experiment device.
Background technique
Buoyancy measurement experiment refers to that buoyancy of the object of the object and lower layer that float in measurement water by water, notification number are
A kind of " buoyancy measurement experiment device " is disclosed in the patent document of " CN205211267U ", mainly includes：Transparent glass water
Slot, the truckle with sucker, connection ring, cotton rope, foam-plastic blocks and dynamometer, the combination of sucker and truckle is one by one by small cunning
Wheel is fixed on sucker, forms the sucker of a pulley, for sucker suction in bottom of gullet, truckle puts on cotton rope, and one end is tied
Foam-plastic blocks, the other end are connected on dynamometer, and foam-plastic blocks are pulled in water toward pull-up and measure it in water by dynamometer
Receive great buoyancy.
It is although able to detect the size of buoyancy of object using the scheme in above patent document, but is asked there are such a
Topic：Because sucker is adsorbed in glass flume, during pulling up weight beam, sucker can inevitably go out
It now loosens, results in the data inaccuracy of measurement in this way, and since sucker is in water, to be just not easy to observation sucker
Whether loosen, so leading to the data of detection can not accurately know whether accurately.
Summary of the invention
In view of the above technical problems, the invention is intended to provide a kind of buoyancy measurement experiment whether loosened convenient for observation sucker
Device.
In order to solve the above technical problem, the present invention provides following technical solutions：A kind of buoyancy measurement experiment device, including
Sink, the sink is interior to be equipped with sucker, and the sucker suction is fixedly connected vertically in the bottom of sink, the upper surface of the sucker
There is connecting rod, the top vertical spacing of the connecting rod is equipped with limit plate, is rotatably connected to pulley between two pieces of limit plates,
Cotton rope is cased on the sliding slot of the pulley, one end of the cotton rope is connected with foam-plastic blocks, the other end connection of the cotton rope
There is dynamometer, it is characterised in that：The interior bottom of the sink is fixedly connected with support rod, the top connection of the support rod vertically
Have a holding block, one end of the holding block is located at the top between two pieces of limit plates and being located at pulley, the holding block with
Gap is reserved between two pieces of limit plates.
The working principle and its advantages of this programme：
Buoyancy measurement experiment device in the present invention, in use, first by sucker suction in the bottom of sink, then in water
Water is filled in slot, because the upper surface of sucker is fixedly connected with connecting rod vertically, the top vertical spacing of connecting rod is equipped with limit
Plate is rotatably connected to pulley between two pieces of limit plates, and is cased with cotton rope on the sliding slot of pulley, and one end of cotton rope is connected with
Foam-plastic blocks pull the dynamometer on the cotton rope other end then up, foam-plastic blocks during dynamometer are pulled just to exist
Sink in sink, and then the buoyancy of foam-plastic blocks can be measured, and because the interior bottom of sink is fixedly connected with vertically
Support rod, the top of support are connected with holding block, and one end of holding block is located at the top between two pieces of limit plates and being located at pulley,
There are gaps between holding block and two pieces of limit plates, and when sucker loosens, sucker will float upwards, and then will be even
Extension bar is held up upwards, and such pulley will be contacted with holding block, since holding block supports pulley, and then does not lead to pulley just not
It is able to rotate, is not capable of measuring the buoyancy of foam-plastic blocks thus, and then can timely find that the sucker in sink occurs
It loosens.
Further, the connecting rod is located at the center of the upper surface of sucker.Which adds the stability of support rod.
Further, the sink is made of transparent material.The situation in observation sink can be thus easily facilitated, and is surveyed
It is more intuitive during amount buoyancy.
Further, the support rod is detachably connected with sink.Support rod in conjunction with water, inevitably will appear damage for a long time
It is bad, and then need replacing, support rod and sink are used into dismountable connection type, replacement is got up just more convenient.
Further, the sink is equipped with drainpipe, and the drainpipe is equipped with valve.After finishing experiment, need water
Water discharge in slot, by the drainpipe on sink, then opens valve, this makes it possible to timely by the discharge in sink.
Further, the surface of the cotton rope is equipped with waterproof layer.Bubble can inevitably damage, online cotton rope in sink for a long time
The surface of rope is equipped with waterproof layer, effectively avoids cotton rope and is damaged, extends the service life of cotton rope.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of buoyancy measurement experiment device of the present invention；
Fig. 2 is the cross-sectional view in Fig. 1 at A-A.
Specific embodiment
Below by the further details of explanation of specific embodiment：
Appended drawing reference in Figure of description includes：Sink 1, sucker 2, connecting rod 3, limit plate 4, pulley 5, cotton rope 6, bubble
Foam unit of plastic 7, dynamometer 8, support rod 9, holding block 10, drainpipe 11, valve 12.
Embodiment is substantially as shown shown in Figure 1 and Figure 2：A kind of buoyancy measurement experiment device, including be made of transparent material
Sink 1, sucker 2 is equipped in sink 1, sucker 2 is adsorbed on the bottom of sink 1, and the center of the upper surface of sucker 2 is fixed vertically
It is connected with connecting rod 3, the top vertical spacing of connecting rod 3 is equipped with limit plate 4, is rotatably connected to pulley between two pieces of limit plates 4
5, cotton rope 6 is cased on the sliding slot of pulley 5, and one end of cotton rope 6 is connected with foam-plastic blocks 7, and the other end of cotton rope 6 is connected with dynamometry
Meter 8, the interior bottom of sink 1 is threaded with support rod 9 vertically, and the top of support rod 9 is connected with holding block 10, holding block 10
One end is located at the top between two pieces of limit plates and being located at pulley 5, is reserved with gap between holding block 10 and two pieces of limit plates 4；
Sink 1 is equipped with drainpipe 11, and drainpipe 11 is equipped with valve 12；The surface of cotton rope 6 is equipped with waterproof layer.
Then buoyancy measurement experiment device in the present invention exists in use, sucker 2 to be adsorbed on to the bottom of sink 1 first
Water is filled in sink 1, because the upper surface of sucker 2 is fixedly connected with connecting rod 3 vertically, the top vertical spacing of connecting rod 3 is set
There is limit plate 4, pulley 5 is rotatably connected between two pieces of limit plates 4, and be cased with cotton rope 6 on the sliding slot of pulley 5, and cotton rope 6
One end be connected with foam-plastic blocks 7, then up pull 6 other end of cotton rope on dynamometer 8, pull dynamometer 8 process
Middle foam-plastic blocks 7 just sink in sink 1, and then can measure the buoyancy of foam-plastic blocks 7, and because sink 1
Interior bottom is fixedly connected with support rod 9 vertically, and the top of support is connected with holding block 10, and one end of holding block 10 is located at two pieces of limits
Between the plate of position and positioned at the top of pulley 5, there are gaps between holding block 10 and two pieces of limit plates 4, when sucker 2 loosens
When, sucker 2 will expand, and then connecting rod 3 is held up upwards, and such pulley 5 will be contacted with holding block 10, due to holding block
10 support pulley 5, and then cause pulley 5 that cannot rotate, and are not capable of measuring the buoyancy of foam-plastic blocks 7 thus, in turn
It can timely find that loosening occurs in the sucker 2 in sink 1.
